Description
本申请涉及交通领域，更具体地，涉及一种飞行汽车。
飞行汽车是汽车和飞机结合的产物，很多国家的公司机构都对其进行了相应的研究。在现有的飞行汽车的设计中，大致分为两类一种是以汽车+固定翼飞机的方式，另一种是汽车+直升机的方式。两种方式都将汽车与飞机的功能独立开来，在汽车功能阶段，飞行的部分装置构造就是多余的，而在飞行阶段，汽车的部分功能则变成多余的，在动力装置上更是二者完全独立开来，增加了重量又增加了成本。还有一种收缩横列式螺旋桨的方案，该方案在汽车模式与普通汽车相同，在飞机模式，则先将收缩于车身内的两个横列式螺旋桨释放出来，此时，飞行汽车的构型与横列式双桨直升机相同，实现汽车的垂直起降，而当到达安全高度之后，螺旋桨进行角度的旋转，此时转化为类似美国V-22鱼鹰的状态，利用机翼产生升力。而在着陆时，可以选择垂直着陆，也可以选择滑跑。该方案相当于汽车+倾转旋翼机的方式来实现飞行汽车的功能。在安全性、功能性等方面高于其他飞行汽车的设计。
但是，该方案仍旧存在着汽车动力与飞机动力不同的浪费，同时，对于机翼和螺旋桨的折叠收缩需要占用大量的空间，影响乘用空间以及汽车阶段的性能。
针对相关技术中存在的问题，本申请的目的在于提供一种可在汽车模式和飞机模式使用同一动力机构的飞行汽车。

根据本申请，第一涵道风扇的数量和第二涵道风扇的数量分别为两个，车体具有从车头至车尾的对称线，两个第一涵道风扇相对于对称线对称设置，两个第二涵道风扇相对于对称线对称布置。
根据本申请，车体上沿着对称线设置有支撑轴，支撑轴上设置有多个支座，两个第一转轴和两个第二转轴分别对应穿设在多个支座上并贯穿第一涵道风扇和第二涵道风扇。

应当理解，图中示出的车体是简化后的车体，本申请中的车体10可以是如普通汽车那样带车轮的车体与是可以是根据飞行需要改造后的车体。
参照图1，第一涵道风扇20具有沿着垂直于第一中心轴线23的方向贯穿第一涵道风扇的侧壁21的第一转轴22，第一传动机构40与第一转轴22连接以使得第一中心轴线23在竖直方向G和水平方向B之间切换。

参照图1，第二涵道风扇30具有沿着垂直于第二中心轴线33的方向贯穿第二涵道风扇的侧壁31的第二转轴32，第二传动机构50与第二转轴32连接以使得第二中心轴线33在竖直方向G和水平方向B之间切换，第二传动机构50的结构与第一传动机构40的结构相同。第二涵道风扇30具有与第一涵道风扇20相同的结构和部件，由于附图角度的原因，有些部件被遮挡无法看见，可以参照上述的第一涵道风扇20的结构来理解第二涵道风扇30的结构。
参照图1，第一涵道风扇20的数量和第二涵道风扇30的数量分别为两个，车体具有从车头至车尾的对称线14，两个第一涵道风扇20和两个第二涵道风扇30分别在对称线14的两侧对称布置。也就是说，两个第一涵道风扇20在车头在对称线14的两侧对称布置，两个第二涵道风扇30在车尾在对称线14的两侧对称布置。
参照图2，车体10上沿着对称线14设置支撑轴，支撑轴上设置有多个支座11，第一转轴22穿过对应的支座11并贯穿两个第一涵道风扇20，第二转轴32穿过对应的支座11并贯穿两个第二涵道风扇30。支座11还可用于固定第一舵机41和第二传动机构50中的第二舵机，以及支撑第一转轴22和第二转轴32，并且在用于支撑第一转轴22和第二转轴32的支座11上设置有导向台12，导向台12对应的传动杆和摇臂的铰接处提供导向面13用于在摇臂摇摆时对摇臂起到沿着前后方向的导向作用，防止摇臂沿着在转轴的延伸方向上的摇摆。

参照图1，当第一中心轴线23和第二中心轴线33均处于竖直方向G时，第一涵道风扇20和第二涵道风扇30提供垂直升力，使飞行汽车处于飞机模式。
参照图4和图5，飞行汽车还包括起落架和多个车轮，分别装设在车体的底部，起落架在飞行汽车降落时支撑车体，车轮在第一涵道风扇和第二涵道风扇提供动力的情况下转动而实现飞行汽车的陆地行驶。当第一中心轴线23和第二中心轴线33中的至少一者处于水平方向B时，第一涵道风扇20或/和第二涵道风扇30提供陆地行驶动力，使飞行汽车处于汽车模式。具体而言，汽车模式包括普通汽车模式和高速汽车模式；当飞行汽车处于普通汽车模式时，第一涵道风扇20的进风口23的第一中心轴线23或第二涵道风扇组件30的第二中心轴线33与水平方向B一致；当飞行汽车处于高速汽车模式时，第一涵道风扇组件20的第一中心轴线23和第二涵道风扇组件30的第二中心轴线33与水平方向B一致。也就是说，高速汽车模式相对于普通汽车模式，飞行汽车的行驶速度相对较高。在图4所示的普通汽车模式下的地面行驶过程中，位于车头的第一涵道风扇20的第一中心轴线23处于与水平方向B一致的状态，其风扇工作，以提供前进的动力；而位于车尾的第二涵道风扇30的第二中心轴线33处于与竖直方向G一致的状态，其风扇不工作，不提供前进的动力。在汽车模式的行驶过程中，通过油门调节风扇转速，进而控制加速与减速。如果需要汽车高速行驶，则开启高速汽车模式，则将位于车尾的第二涵道风扇组件30也转动为其第二中心轴线33与水平方向B一致的状态，以进一步提供前进的动力。有益地，在汽车模式下，飞行汽车没有独立的发动机或其他动力源来提供动力，而仅靠第一涵道风扇20和/或第二涵道风扇30提供动力。从而不论飞机模式还是汽车模式，本申请的飞行汽车均采用相同的动力，提高了结构和动力的利用率。
在一优选的实施例中，飞行汽车包括一控制装置（未示出），控制装置设在车体10上并分别与第一涵道风扇20和第二涵道风扇30电连接，当处于汽车模式时，控制装置可控制位于对称线14两侧的第一涵道风扇20和第二涵道风扇30具有不同的转速，以实现飞行汽车在陆地行驶时的转向。
本申请提供一种汽车和飞机相结合的交通工具的完美结合的解决方案。通过以涵道风扇为动力，针对汽车和飞机两种不同的状态，进行涵道风扇结构布局的切换，进而实现汽车和飞机两种功能。本申请的飞行汽车可应用于城市交通系统领域，可以针对现在的交通拥堵提供一种解决方案，而且还可作为个人飞行体验类旅游领域，带给人们飞行和驾驶的快乐，也可以作为城市救援的快速解决者。本申请的飞行汽车在汽车模式和飞机模式动力共享，可以大幅度的减轻飞行汽车的重量，同时降低成本，提高飞行汽车的安全性、可靠性。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
